YSCFC24 SERIES FLATBOTTOM GAS FRYERS
CHAPTER 2: PRE-INSTALLATION
2.1 GENERAL
A. Installation of any gas-fired equipment should be performed by qualified personnel.
B. A manual gas shut-off valve must be installed in the gas supply line between the
appliance(s) and the main gas supply for safety and ease of future service.
2.2 CLEARANCES
The appliance area must be kept clear of all combustibles. Each unit is design-certified for the
following installations:
1. Commercial use only (not for household use).
2. For installation on a combustible floor when equipped with the factory supplied 5" casters (6"
work height).
3. Areas with a minimum clearance of 6" side, 6" rear and 6" from the floor for combustible
construction. YSCFC24 Series flatbottom gas fryers must be installed with the casters provided.

WARNING
Local building codes will usually not permit a deep fat fryer with
an open tank of hot oil to be installed immediately next to an
open flame of any type, whether a broiler or the open burner of a
range. Check local codes before beginning installation.
2.4 AIR SUPPLY & VENTILATION
The area around the appliance must be kept clear to avoid airflow obstruction of
combustion and ventilation air as well as for ease of maintenance and service. Never use
the interior of the fryer cabinet for storage.
A. Means must be provided for any commercial, heavy-duty cooking appliance to exhaust
combustion wastes to the outside of the building. It is essential that a deep fat fryer be
located under an approved exhaust hood or that an exhaust fan be provided in the wall
above the unit, as exhaust gas temperatures are in the vicinity of 450°F-600°F (232-343°C).
Exhaust hoods and air conditioning systems can produce slight air drafts in the room, which
can interfere with pilot or burner performance. Air movement patterns should be defined
during installation. If pilot or burner problems arise or persist, alteration of air movement
patterns will be required.
B. Do not place the flue outlet of the fryer directly into the plenum of the hood; fryer gas
combustion will be affected.
C. Exhaust temperatures, in addition to the open tank of hot oil, make the storage of anything
on shelving over or behind the fryer unsafe.
D. Filters and drip troughs should be part of any industrial hood. Consult local codes before
installing an industrial hood.
2.5 ALTITUDE
The input rating (BTU/hr) of YSCFC24 Series fryers is rated for elevations up to 2,000 feet (610
Meters). For elevations above 2,000 feet (610 Meters), the rating should be reduced four percent
for each additional 1,000 feet (305 Meters) above sea level.

CHAPTER 3: INSTALLATION INSTRUCTIONS
3.1 UNPACKING
Check that the container is upright. Use outward prying - no hammering - to remove the carton.
Inspect the fryer(s) for visible damage. If such damage has occurred, do not refuse shipment, but
contact the carrier and file the appropriate freight claims.
FRYMASTER FRYERS EQUIPPED WITH LEGS ARE FOR PERMANENT
INSTALLATION. FOR MOVEABLE OR PORTABLE INSTALLATION, FRYMASTER
OPTIONAL EQUIPMENT CASTERS MUST BE USED.
QUESTIONS? CALL 1-800-551-8633.
3.2 CASTERS
Casters should be installed near where the appliance is to be used. After unpacking, raise the unit
approximately 12 inches to attach casters to the couplings. Lower the fryer gently to prevent
damaging the casters and internal mounting hardware. Use a pallet lift jack if available, when
installing casters. Systems ordered with optional casters come with casters installed.
3.3 POSITIONING
Do not push against any of the edges of the unit to adjust its position. Lift fryer slightly and place it
where it is to be installed. Although all metal parts are deburred during manufacture, accidents
could occur if the fryer (or a lineup) should move suddenly when being pushed into position by
hand. Pushing a unit (rather than using a lift jack) also increases the probability of bending the leg
spindles or the internal coupling connectors.
3.4 LEVELING
A. A spirit level should be placed across the top of the fryer and the unit leveled both front-to-
back and side-to-side (side-to-side adjustment is not possible on units equipped with
casters). Erratic burner combustion, inefficient unit operation and oil-drainage problems are
some of the problems caused by unleveled fryers. In addition, units may not match up
properly in a multi-unit battery.
B. If the floor is smooth and level, minor height adjustments can be made with the screw
adjustment on each leg. Adjust to the high corner and measure with the spirit level. Fryers
equipped with casters have no level adjustment options. The floor area where casterequipped units are installed must be level.
3-1
3.5 GAS CONNECTION
The gas supply (service) line must be the same size or greater than the inlet line of the appliance.
YSCFC24 Series gas fryers use a 3/4" NPT (Schedule 40) inlet; however, the gas supply lines must
be sized to accommodate all the gas-fired equipment that may be connected to that supply.
Consult your contractor, gas company or supplier, or other authorized agent for inspection and
installation. Sealant on all pipe joints must be resistant to LP gas.
3.5.1 Manual Shut-off Valve
The manual shut-off valve must be installed in the gas service line ahead of the appliance in the
gas stream and in a position where it can be reached quickly in the event of an emergency.
3.5.2 Gas Pressure Regulation
All commercial cooking equipment must have a pressure regulator on the incoming service line for
safe and efficient operation, since service pressure may fluctuate with local demand. External
regulators are not required on YSCFC24 Series gas fryers as the pilot safety control valve regulates
gas pressure. If the incoming pressure is in excess of 1/2" PSI (3.45 kPa), a step-down regulator
will be required.
Check burner manifold pressure with a manometer. Natural gas units require 4" W.C. gas pressure
and propane (LP) units require 11" W.C. gas pressure. If a pressure regulator vent line is installed,
it should be vented to the outside of the building in accordance with local codes, or ANSI Z223.1 (or
current revision).
Disconnect the fryer/individual shut-off valve from the main gas supply when pressure testing
systems in excess of 1/2" PSI (3.45 kPa). When pressure-testing systems equal to or less than 1/2"
PSI (3.45 kPa), isolate the fryer by closing the manual control valve prior to testing.
3.5.3 Gas Valve/Orifice Configuration
YSCFC24 Series gas fryers can be connected to either natural or propane gas, depending on the
configuration. The safety control valve and orifices are installed at the factory for the appropriate
gas. If the gas valve and/or orifices require adjustment or conversion in the field, only authorized
service personnel with proper test equipment should make the adjustments or conversion.
3.5.4 Rigid Connections
YSCFC24 Series gas fryers come as single units or in multi-unit batteries. Inspect all installersupplied gas-intake pipe(s) for dirt, metal dust and other foreign material. Use compressed air to
clear foreign material from supply piping before installing into a service line. Failure to do this can
result in clogged orifices and gas valve damage when gas pressure is applied.
All connections must be sealed with a joint compound suitable for LP gas, and all connections must
be tested with a soapy solution before lighting any pilots. DO NOT USE AN OPEN FLAME TO
CHECK FOR LEAKS! Detecting gas leaks with an open flame is not only dangerous, but will often
miss small leaks that a soapy solution would detect.
3-2
3.5.5 Flexible Couplings, Connectors
If the unit is to be installed with flexible couplings and/or quick-disconnect fittings, the installer must
use a heavy-duty, AGA design-certified commercial flexible connector. The connector must be at
least 3/4" NPT (with suitable strain reliefs) in compliance with the Standard for Connectors for
Movable Gas Appliances, ANSI Z21.69-1987 (or latest edition). Quick-disconnect devices must
comply with the Standard for Quick-Disconnect Devices for Use with Gas Fuel, ANSI Z21.41-1989
(or latest edition). DOMESTIC CONNECTORS ARE NOT SUITABLE!
If multi-unit batteries are installed on casters, the same ANSI Standards apply. In addition, some
means must be provided to limit the movement of the appliances without depending on the
connectors or associated piping.
3.6 ELECTRICAL CONNECTIONS
The wiring diagram is attached to the inside of the fryer door. Wiring diagrams are also included in
this manual for reference. Always consult the wiring diagram mounted on the fryer when
troubleshooting or repairing the fryer. YSCFC24 Series gas fryers require 120 volts, and are
equipped with a 16-3 SJT grounded flexible power cord for direct connection to a 120-volt power
supply. Amperage for each unit depends on the accessories supplied with the unit.
WARNING
(Electrical Grounding Instructions)
This appliance is equipped with a three-prong (grounding) plug for your protection
against shock hazard, and should be plugged directly into a properly grounded
three-prong receptacle. Do not cut, remove, or otherwise bypass the grounding
prong on this plug!

1. Fill the frypot with hot or cold water (non-KFC
line scribed in the back of the frypot. Main burner operation and initial controller calibration can
be checked during this step.
NOTE: In KFC co-branded locations, oil must be used in place of water for burner testing.
2. Set the Thermatron dial to 200°F (93°C), just below that of boiling water.
3. Turn the fryer power switch on. The blower will activate and the main burner will ignite.
4. Check the main burners and, if necessary, adjust the burner dampers at each burner (Figure 2,
Page 4-4) to obtain the best flame characteristics. An optimum flame should be blue at the
base, 2-½ - 3" in height, and have a reddish-white tip ¾ to 1" in height. To adjust, loosen the
screw of the air shutter, and open or close the shutter until the burner flame matches the
optimum flame description above. Tighten the shutter screw, and repeat for all burners. The
flame should be straight and not pulling to the rear of the fryer. If the flame is pulling to the rear,
inspect the main rear baffle for heat damage and replace if necessary.
5. The burners should shut off just at the water starts to boil.
6. When satisfied that the burners and controller are operating properly, drain the frypot of water
and dry thoroughly.

4.5 FILLING THE VAT WITH SHORTENING
DANGER
NEVER MELT A SOLID BLOCK OF SHORTENING BY PLACING IT WHOLE INTO THE
FRYPOT. FRYPOT DAMAGE CAN OCCUR AND THE CHANCE OF FLASH-POINT
FIRE INCREASES.
1. Cut the block of shortening into small pieces and pack into the frypot bottom. Do not set a
whole block of shortening into the frypot. ENSURE THE BOTTOM OF THE FRYPOT IS
COMPLETELY COVERED WITH SHORTENING BEFORE TURNING UNIT ON. Continue
packing the frypot to the lower OIL LEVEL line scribed into the back of the frypot.
2. Turn the Thermatron controller to the desired temperature after the frypot is properly filled with
shortening. The burners will cycle in melt cycle mode until approximately 145°F (63°C), and
then remain on until setpoint temperature is attained. The “green” indicator light (heat indicator)
will cycle on and off at setpoint temperature.
4.6 FINAL PREPARATION
Before starting operation, turn the Thermatron controller to the desired shortening temperature, wait
for the temperature to stabilize, and then check with a high-quality immersion thermometer.
WARNING
NEVER MOVE A FRYER FILLED WITH HOT LIQUID.
DO NOT GO NEAR THE AREA DIRECTLY OVER THE FLUE OUTLET WHEN THE MAIN
BURNERS ARE OPERATING.
ALWAYS WEAR OIL-PROOF, INSULATED GLOVES WHEN WORKING WITH HOT OIL.
ALWAYS DRAIN HOT OIL INTO A METAL CONTAINER...HOT OIL CAN MELT

CHAPTER 5: DAILY OPERATION/FILTRATION
5.1 OPENING
At opening, check the fryer for:
1. Combination or main gas valve "OFF".
2. Power Switch "OFF" (If so equipped).
For lighting the fryer, see Section 4.2 (Section 4.3 if equipped with Electronic Ignition).
5.2 GENERAL OPERATIONS STATEMENT
See the company Operations Manual for operating instructions prior to using the YSCFC24
Series gas fryer. Operating instructions in this chapter are intended for temporary use as a
guide in absence of the company Operations Manual.
5.3 FILTERING
Shortening should be filtered at least daily, or more frequently if cooking is heavy. This assures the
longest life possible for the shortening, imparts a better flavor to the product and minimizes flavor
transfer. To ensure shortening quality, filtering and daily maintenance should be performed
according to company Operations Manual
.
WARNING
LEAVE FRYER OFF FOR A MINIMUM OF 10 MINUTES PRIOR TO FILTERING TO
ALLOW FRYPOT HEAT TO DISSIPATE. FRYPOT DAMAGE CAN OCCUR IF THE
SHORTENING IS DRAINED IMMEDIATELY AFTER TURNING FRYER OFF.
WARNING
WHEN OPERATING THE FILTRATION SYSTEM, NEVER LEAVE THE FILTER
UNATTENDED. THE ACTION OF THE SHORTENING MOVING THROUGH THE HOSE
LINES COULD JOLT A FLEXIBLE RETURN HOSE OUT OF THE FILTER PAN,
SPRAYING HOT SHORTENING AND CAUSING SEVERE BURNS.
DANGER
THE CRUMB TRAY IN FRYERS EQUIPPED WITH A FILTER SYSTEM MUST BE
EMPTIED INTO A FIREPROOF CONTAINER AT THE END OF FRYING OPERATIONS
EACH DAY. SOME FOOD PARTICLES CAN SPONTANEOUSLY COMBUST IF LEFT
SOAKING IN CERTAIN SHORTENING MATERIAL.
